Lanjun glaze

Abstract

The invention discloses Lanjun glaze. The Lanjun glaze is prepared from, by weight, 40-50 parts of original chemicals, 10-14 parts of quartz, 14-18 parts of calcite, 4-6 parts of talc, 1.4-1.6 parts of iron oxide, 0.4-0.6 part of cobalt oxide, 4-6 parts of copper ore, 8-12 parts of a zinc frit, 0.4-0.6 part of bone ash and 6-10 parts of plant ash. In the glaze materials, feldspar in a traditional recipe is substituted by the original chemicals, part of raw glaze materials is substituted by the zinc frit, iron oxide and cobalt oxide coloring and coloring agents are adopted, content of aluminum and potassium is increased, and firing range is extended; the Lanjun glaze of high quality is obtained with a coal burning or charcoal-burning traditional method, high yield rate can be achieved, and economic and artistic values are increased.

Description

technical field [0001] The invention belongs to the technical field of Jun porcelain production, and in particular relates to a Lan Jun glaze and a preparation method thereof. Background technique [0002] Jun porcelain is one of the five famous porcelains of the Song Dynasty in my country. It is famous for its unique "kiln change" glaze color. It is a unique national treasure porcelain in Shenhou Town, Yuzhou City, Henan Province. The traditional blue glaze in Jun porcelain uses natural cobalt ore as the colorant, and in addition to cobalt oxide, it also contains iron oxide. In order to obtain a high yield rate, modern Junlan glaze is generally made by adding oxidized chemical raw materials and firing with gas. Due to the relatively simple atmosphere of gas firing and the use of chemical raw materials, there is a lack of natural ore coloring agents. The addition of a variety of metal elements leads to the monotonous and gorgeous glaze color of the fired Lanjun glaze, which...
